flexit_bacnet's Issues

Feature request: add api for feature "free cooling"

In the Flexit app there is a function/feature for free cooling. It would be nice if this could be toggled from this library and Home Assistant.

Using wrong device id will return integer 0 instead of string from serial_number and device_name attributes

If you run this code

import asyncio
from flexit_bacnet import FlexitBACnet

async def main():
    device = FlexitBACnet('192.168.1.11', 3) # device id = 3
    await device.update()

    print('Device Name:', device.device_name) # will return 0
    print('Serial Number:', device.serial_number) # will return 0

if __name__ == "__main__":
    asyncio.run(main())

According to function type hints these should only return str. How this should be fixed? I could also take a stab at this if needed.

Air filter replace timer reset uses wrong MULTI_STATE_VALUE

Air filter replace timer reset uses MULTI_STATE_VALUE = 613, but it should be MULTI_STATE_VALUE = 609 according to Flexit.

Extract air temperature (device.extract_air_temperature) is always at 0.0, while on the display unit it is showing values other than 0C.
Also Humidity is shown on display unit but none of the device.room_x_humidity reports any other value then 0

flexit_bacnet.bacnet.DecodingError: unsupported response type: 7

Trying to implement sensors in the home assistant integration flexit_bacnet craches after a while (probably when polling sensor values). It seems to work the first time.

Here is the added code in core: lellky/core@3cfb6b9

This is the error output:

Auto discovery support

Could this feature to be possible to add? I'd be willing to help on this one if needed. I opened this issue here so we can collaborate publicly and share information which others can also see.
